WELL-DRILLING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 748,517, dated December29, 1903.

V Application led April 10, 1903. Serial No. 152,065. ('No model.)

:To all whom it 'may concern:

Beit known that we, FRANK R. MCKEE and EMMA E.MCKEE,citizens of theUnited States, residing at Coshocton,in the county of Coshocton andState of Ohio, have invented certain new and useful Improvements inWell-Drilling Machines, of which the following is a specification.

This invention provides a machine for sinking deep wells by the use ofcable, drills, and spudding mechanism, the object being to facilitatehandling and have the machine at all times under control.

The mechanism admits of the drill-rope at the beginning being jogged andat the latter stages of the operation being attached to thewalking-beamo as to be reciprocated thereby. Clutches are dispensed withand brakeshoes arranged to hold the drums for the drill and bailingcables when it is required to prevent the rope paying off therefrom.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modication,still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figure1 is a side elevation of a machine for drilling deep wells constructedin accordance with and embodying the vital features of the invention.Fig. 2 is a top plan view of the machine,the derrick and walking-beambeing omitted. Fig. 3 is a side view showing the drums for theoperating-cables and the mountings therefor on a larger scale. Fig. 4 isa view similar to Fig. 3, showing the bearings shifted. Fig. 5 is afront view of one of the drums, showing the eccentric bearing therefor.Fig. 6 is a detail view in elevation of the crank-wheel for imparting ajogging movement to the drill-cable. Figs. 7 and 8 are detail views ofthe crank-arm and jogging-wheel applied thereto. Fig. 9 is a detail viewof a brake-shoe and the means for adjustng same to compensate for wear.

Corresponding and ,like parts are referred to in the followingdescription and indicated in all the views ofthe drawings by the samereference characters.

The operating mechanism is shown mounted upon` a truck, so as to renderthe machine readily portable, the position of the machine being adapted`to be fixed in any manner. The bed 1 of the truck or machine maybe ofany construction, according to the design of the machine and the specialarrangement of the parts. A derrick 2 is fitted to the rear end of theframe and is strengthened by braces 3 and 4. This derrick may be of anyheight, according to the depth of well to be drilled, and is provided atits upper end with `sheave-pulleys 5 and 6, over which cables 7 and 8pass. The derrickis adapted to be raised and lowered preferably by meansof the mechanism mounted upon the frame. The walking-beam 9 is fulcrumedintermediate of its ends to Samson-post 10, rising from the rear end ofthe machine and stayed by braces 11. The inner end of walking-beam `9has pitman'12 pivoted thereto,and the outer end is provided with theusual grip (not shown) `for receiving the drill-cable when spudding,connection 13 suspending the gripl convenient point by means of-rod 21,said rod being adapted to be secured so as to hold pulley 16 in thedesired position. A shaft 22 is journaled parallel toshaft 14 and isprovided with Vdrum 23 and friction-pulley 24 and is mounted at one endin eccentric bearing 25, from which lever 26 projects, and is connectedto operating-rod 27, extended within convenient reach and adapted to besecured so as to hold pulley 24 in the desired position. Brake-shoe 28is located in Vthe rear of pulley 24, and the latter is adapted to bethrown into contact witheither pulley 19 or brake-shoe 28, according asdrum 23'is to be positively driven or held fixed. Cable 8 is adapted towind upon drum 15 and carries IOO sand-bucket 29 for hailing the Well.Cable 7 is adapted to wind upon drum 23 and is adapted to have thedrilling-tools connected thereto. The drill-cable is either jogged or.has a vertical reciprocating movementimparted thereto, as may bedesired. i Driveshaft 30 is located intermediate of shafts 14 and 22 andis provided at one end with drivepulley 19 and at its opposite end withbandpulley 3l, to which motion is imparted when the machine is inoperation from any source of power, said shaft 30 being continuouslydriven. j

Shaft 32 is located near the rear end of the machine and is providedwith band-pulley 33 and is connected by drive-belt 34 with bandpulley 35of shaft 30. Crank-arm 36 is secured to shaft 32 and is provided with aseries of openings 37 to receive wrist-pin 38 in any selected position,whereby the stroke of the drilling-tool may be regulated according tothe distance of wrist-pin 38 from the axis of shaft. 32. The wrist-pin38 may receive the lower end of pitman 12 when walkingbeam 9 is to beoperated or may be provided with wheel 39 for imparting a joggingmovement to the drill-cable when the tool is to be operated by a joggingmotion of the cable. The jogging-wheel 39 is grooved in its periphery,so as to receive drill-cable 7 andv prevent displacement thereof. Adirection-pulley 40 is located in longitudinal alinement withjogging-wheel 39, so as to prevent lateral displacement of thedrill-cable therefrom when the machine is in operation.

The engine (not shown) maybe of any make, such as commonly used fordrilling operations, and may be mounted upon the same' frame with thedrilling mechanism or be independent therefrom, so as to be used inother connections, this feature of construction being unimportant. Theshaft 30 being continuously driven, motion may be taken therefrom foroperating drums 15 and 2 3 by operating-rods 21 and 27 to throw pulleys16 and 24 into contact with drive-pulley 19, thereby winding the cableon the respective drum, so j as to lift either the tool or thesand-bucket. The drums are held stationary by throwing the pulleys intocontact with the coperating brake-shoes. When the pulleys 16 and 24occupy a position intermediate of drive-pulley 19 and their brake-shoes,the cables may pay off or unwind therefrom to lower either thedrilling-tool orthe hailing-bucket. DuringV the first stages vofdrilling the well it is preferred to operate the drill by jogging theoable,vthis operation vbeing effected by disconnecting pit-man 12 fromcrank 36 and applying wheel 39 to said crank and passing the drill-cable7 beneath said wheel, as indicated in Figs. 1 and 6. When the well hasreached ak comparatively great depth, the joggingwheel 39 is removed andpitman 12 connected to crank 36, the drill-rope being connected to vthepart 13 at the outer end of walking-beam `9 in any convenient way. Thedrill-rope is run o from drum 23 as the work progresses by throwingpulley 24 away from brake- 'shoe 28.. Y

The brake-shoes are pivoted at their lower ends to the frame of themachine, as shown at 41, and have adjustable connection at their upperends to braces 42, whereby provision is had for taking up Wear.

Having thus described the invention, what is claimed as new is Inwell-drilling machinery, the combination of a drive-pulley, a drum forreceiving the drill-cable, a brake-shoe, a pulley connected lwith saiddrum and adapted to be thrown into icontact with either saiddrive-pulley or the v'brake-shoe or to an intermediate position, a shaft32 connected with and receiving motion Efrom the shaft carrying theaforementioned ,drive-pulley, a crank attached to the inner 'endof theshaft 32, a pulley having adjustable connection with the said crank and.adapted to operate the drill-cable and the tool :attached thereto, anda pulley applied to the iframe in line with the pulley carried by thesaid crank to hold the drill-cable in line there- `with, substantiallyas specified.

In testimony whereof We affix our signatures in presence of twowitnesses.
